Tasyaiva hetoḥ prayateta kovidaḥ na labhyate yad bhramatām upary adhaḥ. We are wandering upary-adaḥ. Upary-adhaḥ. Upary means sometimes we are going in the higher planetary systems, Brahmaloka, Janaloka, Satyaloka, sometimes going downward, Tala, Atala, Vitala, Pātāla, Rasātala. Or sometimes higher species of life, sometimes lower species of life. In this way, we are wandering according to our karma. This is material existence. Caitanya Mahāprabhu therefore says,
- ei rūpe bhramāṇḍa bhramite kono bhāgyavān jīva
- guru-kṛṣṇa kṛpāya pāya bhakti-latā-bīja
- (CC Madhya 19.151)
A living entity is wandering in this way, sometimes on the higher level, sometimes on the lower level, but he's changing one chapter, another, one chapter, another. That is not very good, to repetition of birth and death. So a living entity if he's very fortunately, fortunately he meets some good association, good devotees, then his life changes.
